## Discrepancy

(CAN) AN AC CARRIED OUT AN INFLIGHT SHUTDOWN OF THE NR 1 ENGINE DUE TO LOSS OF OIL PRESSURE. AFTER LANDING THE CREW NOTICED OIL STREAKED DOWN BOTH SIDES OF COWLING AND A SIGNIFICANT AMOUNT DRIPPING FROM DRAIN VENTS.  MAINTENANCE FOUND ON THE NR 1 ENGINE, THE OVERSPEED GOVERNOR HAD AN EXCESSIVE OIL LEAK. THE BOLTS ON THE FLANGE THAT SECURES THE SPRING CASING SUB ASSY TO THE MAIN BODY OF THE OVERSPEED GOVERNOR WERE LOOSE ENOUGH TO BE ROTATED BY HAND. OVERSPEED GOVERNOR REPLACED IAW AMM 61-20-26-000-801 AND 61-20-26-400-801.
